Sounds like a very aggressive schedule. It's a little hard to evaluate without more info about your riding experience, but 85-100/day is a lot more than *most* people do on tour. 60-65/day is more common.+1 Planning 85-100 miles/day is a lot easier sitting at home than actually doing it. Have you ever ridden back-to-back centuries? How about 30 in a row? How about doing them on a loaded bike, over Western mountains or Eastern hills?
That schedule gives you no slack time for sightseeing, mechanical problems or a couple of days of dreadfull weather. I'd plan a less agressive schedule or a shorter ride distance.
